Wow you seem to be experiencing a very tough time. The new relationship you describe sounds incredibly stressful and difficult to deal with.
For all of that, it seems strange that you turn up here looking for help, advice, support, a combination of these things? Then become confrontational when you don't hear what you want - blaming others for not understanding, not seeing things your way.
It seems an odd stance to take unless having fights with anonymous strangers on-line is a form of stress relief for you. I know that when I'm experiencing extreme stress, an argument can be a great way to relieve it - I tend to choose to do that with random strangers who look down on parts of my life - there are plenty to choose from if you are an unmarried, childless woman who works as a computer programmer and believes that dogs have a similar emotional capability to that of humans.

To many people, my life seems strange, small, misguided and sad and sometimes people who don't know me say that to me. Then I feel completely free to explain to them the error of their ways. Fantastic stress relief.
I get the argument as stress relief thing. Better to do it with strangers on the internet than to take it out on those closest to you.
I just wonder if here is a good place for that? It seems to me that the community of poly folks here could well be a good source of help and support to you. Poly isn't all that well known or thought of in wider society and having a group to turn to for help and support in hard times or to share the good times with would seem to me to be a good thing for you to have in your life.
I experience the group who write here regularly as very compassionate and caring as a whole. Also, on the whole, this group is good at managing disagreements and discussing differing view points without falling out. I don't agree with everybody who writes here but that's fine.
I've never felt victimised by anybody here and I'm not even interested in pursuing poly as a relationship style.
A big part of what I got from reading and writing here is that poly is not for me at the moment. I came here after starting a relationship with a man who has had several poly relationships and who spoke about it in very positive terms. I was interested in it and thinking it might be a good idea for me and for our relationship.
After a long time of reading and thinking I concluded that it is not for me. My partner and I are mono and will be for the foreseeable future. He is, of course, free to be poly with my blessing any time he wants to be. If he felt it was right for him again, I am committed to doing the work to shift our relationship to one of friendship so that he can be free to seek poly partners. So far, he says he doesn't want to do that.
I've written here about my thoughts numerous times and - obviously - people here don't tend to agree. Of course not, this is a poly board. The people here tend to feel that poly is good for them or if not for them, that it is something they are okay with a partner being even if they are mono.
My view is completely at odds with most of the folk writing here. Yet I've never felt any of the hostility you say you feel.
I suspect that the hostility you feel is a product of the stress you are under rather than to do with anybody on this board.
I hope that your life becomes more peaceful soon and that you are able to find a more productive way of dealing with your stress. It seems to me that you need the people on this board far more than I do and that it would therefore be a good idea to stop alienating so many of them.
